There is an artistic playground designed by Isamu Yoguchi in Atlanta GA that was constructed in the 1970s. It was recently renovated with money provided by the Herman Miller Foundation. Yoguchi’s design for a swing set is very intriguing.
This design is a bit large and bulky. So I wondered about a smaller, simplified design.
I also have concern about the strictly horizontal supports. Maybe it would be better with A-shaped end supports. Below is another Yoguchi example.
